TIMBER WALL CONSTRUCTION - LIKE LEGO
EFFICIENT WALL MODULES - DURABLE AND ERECTED IN NO TIME AT ALL - as: “open, modular building system concept”, without a finished standard solution.
Older 3-D Image of refugee accommodation
Due to the unsolvable environmental problems in cement production and the extraction of building sand, completely new paths could and should have been taken in the construction sector a long time ago. My approach - sustainable building components in modular construction, as a scalable plug-in system offers a contribution to this.
The system targets markets with:
+ rising construction costs
+ resource scarcity (sand, cement, energy)
+ demand for rapidly erected, reversible buildings
It addresses, among others:
+ temporary and semi-permanent structures
+ infill development and vertical expansion
+ municipal, social, and commercial uses
Differences to conventional construction:
+ drywall construction instead of wet construction
+ dismantability instead of demolition
+ modularity instead of one-of-a-kind designs
+ low weight instead of massive loads
+ reuse instead of disposal
This is a modular building system concept based on commercially available materials and established construction principles. The innovation lies not in individual components, but in their systemic combination, dismantling capability, and scalability.
Depending on the implementation, this can lead to a product portfolio, a licensing model, or a project-based business.
How can these modules be manufactured by prefabricated house manufacturers as well as carpentry/joinery firms?
In this concept, stackable sandwich wall modules form a mobile and deployable variant. The example corresponds to my idea of a garden home, here with 35 m² of superstructure area and a height of 5 metres.
The modules can be produced in a short time and can be joined together using a tongue and groove system, allowing them to be raised together with the upper storey.
Ready for shell construction - with windows, doors and internal staircase - my calculation of the material costs (with May 2023) comes to ~25,000 euros.
Each of the components/elements weighs approx. 25 kg. The modules can be manufactured on site* or delivered prefabricated. As tongue and groove elements, the 80 modules here can be handled by 2 people without the need for a construction crane or scaffolding. Around the base plate and its staggered substructure, the components are installed horizontally, efficiently and quickly.
The modules could be delivered prefabricated. As tongue-and-groove elements, the 80 modules can be handled by two people without a crane or scaffolding. The components are installed horizontally, efficiently, and quickly around the base plate and its staggered substructure* (or strip foundation).
AI-optmiert, Dec:2025:.
Two (~12 mm thick) OSB3 panels** can usually remain in their standard size of 205 x 62.5 or 250 x 125 cm. As a sandwich construction, they are surrounded by OSB strips with a D4-glued finger-joint, resulting in a box shape with a selectable wall thickness. Before being sealed, they are filled with inserted mineral wool panels, ➡️ slightly oversized. After the components are numbered and sealed, the result is ➡️ permanently stable, relatively lightweight, and well-insulated modules; Vapor-permeable ✔ No condensation problems ✔ Fire-resistant ✔ 👉Recyclable and windproof.
On two sides of the module – along the central third – laminated hardwood posts (min. 60×80 mm), which act as concealed load-bearing elements for vertical load transfer, are fully bonded with D4 adhesive and secured with 6-8 timber construction screws Ø6 × 120 mm. Around the other module corner, two hard laminated timber panels are attached along each of its two edges. The two tongue-and-groove sides of this module create a positive interlocking connection during installation. Each module connection is further secured with: ➡️2-4 approved timber construction screws, horizontally concealed in the tongue-and-groove; these are necessary for its wind load capacity. A module approved for construction in this manner enables very rapid wall assembly (with virtually concealed support posts and corner reinforcement: load paths via timber, for multi-story load-bearing capacity: ring beam per story ✔ wind-resistant ✔ airtight ✔ bracing ✔ detachable - 👉as a system, load-bearing, durable, industrially scalable, and structurally sound).
📐 For corner joints of the modules: they are inserted in a staggered pattern. The corner acts like a classic timber frame stud but remains invisible and
👉🏗️ structurally integrates the ring beam (load distribution from the ceiling/roof connection), (➡️Material: Glued laminated timber (glulam) or structural timber (KVH) cross-section: 80 × 160 mm (1–2 stories))*. Result: continuous vertical load path, no OSB compressive load; Posts are laid wood-to-wood. Connection: 2–3 timber screws Ø8 × 160 mm, diagonally offset. Absorbs horizontal forces (wind), prevents buckling.
🔥 Fire protection concept – modular timber wall system. 1️⃣ Protection objective (clearly defined). The building should: have sufficient load-bearing capacity in case of fire, prevent fire spread within the wall, delay fire spread between rooms and floors, and provide occupants with sufficient escape time. ➡️ Target level: REI 30 (optional REI 60 with upgrade). 2️⃣ Wall structure – effective in terms of fire protection 🔹 Base module (load-bearing). From outside to inside: 12 mm OSB3 contributes to the diaphragm effect, chars in case of fire, delays spread. Box frame made of OSB + insulation. Insulation: Cellulose or mineral wool (A1/A2) prevents fire propagation within the wall. OSB3 12 mm (airtight) Interior cladding: Gypsum fiberboard ≥ 10 mm, screwed across the entire surface. ➡️ Result: Load-bearing wall REI 30 realistically achievable with two layers of gypsum fiberboard REI 60. 3️⃣ Load-bearing elements in case of fire 🔸 Integrated laminated timber posts (KVH / BSH / hardwood) cross-section 60 × 80 mm completely enclosed by: OSB insulation interior cladding. ➡️ Burn-off reserve available, wood chars in a controlled manner (~0.7 mm/min). Remaining cross-section remains load-bearing ≥ 30 min. 4️⃣ Insulation materials – Assessment: Insulation material fire class, assessment cellulose (borated), B-s2,d0 very good. Mineral wool A1 optimal. 5️⃣ Module joints, plug-in system & fire barriers 🔥 Problem: Plug-in joints can allow fire spread. ✅ Solution: Mineral wool strips (20–30 mm) in horizontal module joints. Ceiling connections >> Joints inside: covered with gypsum fiber. Joints outside: wood fiber / compression tape (non-combustible). ➡️ No vertical fire spread possible. 6️⃣ Ceilings & Floor Transitions - Construction (from bottom): 12.5 mm gypsum fiberboard, 15–18 mm OSB, ceiling joists with mineral wool. OSB/plank flooring on top. ➡️ Floor slab = fire barrier. Ring beam: completely encapsulated in OSB/gypsum, no exposed wood. 7️⃣ Installations & Penetrations: Principle: No open penetrations through load-bearing modules. Implementation: Pipes: in service channels or service layers, interior wall penetrations: with fire collars or mineral wool + fire-resistant sealant. ➡️ System remains demountable. 8️⃣ Escape & Use (simplified concept). For small buildings (≤ 2 stories): 1 structural escape route is sufficient, windows can serve as a second escape route. Smoke detectors in all living areas. 9️⃣ Building class – realistic classification (D/A). With the above structure: Building class 1–2: no problem. Building class 3: realistic with REI 30. Building class 4: REI 60 + detailed verification required. ➡️ The system is not exotic, but typical for timber construction. 🔧 Minimal upgrade for REI 60 (optional), interior: 2 × 12.5 mm gypsum fiberboard. Posts: cross-section +20 mm. Joints: additional mineral wool battens. ➡️ Minimal additional costs, significant safety gain.
🧠 Summary (compliant with regulations). The modular timber wall system achieves a fire resistance rating of at least 30 minutes (REI 30) through encapsulated load-bearing timber cross-sections, non-combustible insulation materials, interior fire-resistant cladding, and fire-retardant joint design. An increase to REI 60 is possible through additional interior cladding without any system modifications.
Cables and other installations can be discreetly and fire-resistantly concealed on the room side behind gypsum fiberboard strips (as ceiling, corner, and baseboard moldings).
The corner joints could be additionally secured from the inside using 4x4 cm angle profiles (shelf uprights) with perforated holes and wood screws (18 cm long, 5 mm diameter).
The concept relies on easy disassembly and the ability to precisely reassemble the numbered components at another construction site.
A simple wooden stringer staircase leads to the sleeping area on the upper floor, which includes a wardrobe storage area and a 7 m² conservatory.
Three planned horizontal window elements (2 x 0.6 m) and the patio door (1.6 x 1.8 m) provide ample natural light to both interior spaces; forced ventilation is planned***.
The completed building structure is then clad with reed mats, which are attached to counter battens. The mats are first spray-impregnated on both sides with water glass (to protect against weathering and flammability).
Evergreen ivy cuttings can then climb up around the house's base, quickly creating a shading and ventilated green facade. This green facade, made of OSB with integrated mineral wool, provides good insulation against short-wave solar heat gain in summer.
A 5 m² vacuum tube collector is mounted against the south-facing wall. A 500-liter buffer tank above it heats a copper pipe laid as a baseboard. The tank also supplies hot water to the washing machine and dishwasher.
The 50 m² (including overhang) pitched roof can be fully covered with ThinFilm membranes**** or PV panels for household electricity generation. Combined with PV batteries, it can also power a split-system heat pump – such as the award-winning Dimstal eco-smart Inverter – QuickConnect.
Rainwater from the roof is collected in two 200-liter tanks and used to irrigate the vegetable garden.
* Tools required: electric screwdrivers, jigsaws, etc.—result in minimal noise and dust generation.
**Kronply-OSB/3-EN300, for example, offers panels that meet the criteria for use in fire-resistant constructions according to DIN 4102-4 in fire resistance class F30.
***Automatic room ventilation with heat recovery: A 5 m long, 100 mm diameter aluminum flexible duct, concealed behind the ceiling channel, is connected to an interval-controlled fan installed in the 150 mm wall opening. A piece of rigid, zigzag-shaped cardboard inserted into the duct ensures good turbulence of the stale warm air and can achieve a significant temperature equalization with the fresh air flowing in through the rest of the channel. From the branch point of the 100 mm inlet, the air is directed vertically downwards for 2.3 m as a corner channel. The negative pressure created in the room by the 150 mm exhaust fan causes fresh air to flow in automatically at the open end of the corner channel. The channel itself, made of rigid cardboard, with its warm room air directly adjacent to the cardboard, can also achieve a significant temperature equalization with the incoming fresh air.
**** PV films are produced by companies such as: ARMOR solar power films, Heliatek®, Flisom, Alwitra-Evalon cSi®, FirstSolar®, and Nanosolar®.
"The described approach is a modular, evolvable prototype that has been tested in certain aspects, but still requires formal approval as a complete system."

The WOODEN WALL CONSTRUCTION SYSTEM – LIKE LEGO is freely scalable – from tiny houses to multi-storey buildings – and is also suitable for adding storeys to existing buildings. Its low weight, high inherent stability and dry construction method enable fast and cost-efficient implementation.
When properly executed, a very long service life can be expected. At the end of its useful life, all components can be sorted by type for reuse. The concept is an open, expandable building system that represents a sustainable alternative to cement- and energy-intensive construction methods.
Target groups are: (implicit/explicit)
For self-builders
For temporary/mobile architecture
For additions to existing buildings
For public/social infrastructure

This construction method is also well suited for migration needs and reconstruction after war damage!
The consequences of war, flight and displacement are increasing worldwide. Many cities are uninhabitable or uninhabitable and legions of people have no or only miserable living space. However, the usual containers and tents - for people - are not suitable accommodation in the heat or cold; they are also bulky to transport.
Whether as a school, ambulance, office, shop or housing requirement - the construction method described above can be used to save space, especially with storeys. These elements can be set up by 2 - 3 people using N/F plug-in connections to suit the respective room utilisation.
To counteract short-wave solar heating, it is particularly advisable - especially in hot regions - to cover the building with reed mats and shade it with ivy.
Stackable wall modules are a mobile and frequently deployable solution for almost any purpose.
The drawing shows an example of many possibilities.
Here as a multi-purpose building with variable room partitioning. This approach requires only simple hand tools for its construction (as well as for its dismantling for reuse).
These living spaces are based on a foundation-free 120 m² mansard roof, with a central 60 m² communal space arranged around the main room. The total interior space in this example covers 120 m². 63 m² are added as floor areas - divided between the 18 units.
This approach would be suitable for support communities whose aim is to offer refuge and encounters for people in crisis from different walks of life.
The most essential, applicable house rules would be: # ... to respect each other. # ... be there for each other as a "small family" and stick together. # ... to help organise the daily structure and group activities as much as possible.
In this example, the central 60 m² of the NurDach serves as a work and recreation room. Small products can be made there in co-operation or various services can be offered.
Smoking and drinking are only permitted outside the building!
Two of the rooms are reserved as an office (or night-time standby room) and as storage - this would result in 18 units of equal size.
Each of the 16 private rooms has 4 m² of living space measuring 3 m x 1.23 m and a room height of 2.5 m and a small window to the day room. Above this is a 3.5 m² attic room, which is accessible via a folding attic staircase.
All sliding doors to the living area can be locked by their respective occupants. In addition to the bed equipment, it also has a wardrobe, folding table, folding chair, a mini-eco-heater, LED lamps and DAB radio with headphones - as well as an attachable extra bed for children who may also move in; and adjustable ventilation.
Residents can keep their sleeping hours around the clock, but there is a general night's rest from 11 pm to 7 am.
The two WCs located in the canopy, the washbasin and the shower have their 12V LED lighting switched by motion sensors.
The shower water is regulated to be drawn every three minutes so that there is enough hot water for everyone. There is also a washing machine and three fridges for residents to use.
In cold weather, the 10 x 6 metre central room of the "NurDach" also provides a place for children and their parents to play and snuggle up. Screens form a partition from the rest of the space, which all residents can use for their various activities.
The kitchen, dining area and sanitary facilities would be located outside under one roof.
The panels hanging down at the outer edge are rolled up in strong winds. These mats are protected against fire and weathering with a coat of water glass.
There is also a children's play tower with 2 swings, sandpit and slide fenced in by Immergrün under this canopy.
The house and porch would also be surrounded by a hedge, raised beds and berry bushes.
Two 1000 litre hot water tanks are located centrally in the porch - they are connected to the hot water collectors on the south-facing roof. This space is also used by a PV module to supply the 12V consumers with electricity.
Leisure activities include badminton, table tennis and a bookshelf as well as sewing, pottery, language courses, music, painting, dance, gymnastics and more. The carers offer a varied, colourful daily structure - according to their own talents and focus. Whether it's an excursion, singing, meditation or a basic PC course - there are always encounters and useful things on the programme.
By coming together on a daily basis to work and spend leisure time together, there are also interdenominational and non-political human conversations.
The project costs a total of around €50,000 per unit.
Most of the goods would come from DIY stores, which would then also appear as the main donors.

Solar thermal energy, for example, is a very important building block here, along with other aspects: "Why generate electricity first and then heat from it? That's what solar thermal energy is for." Dr Gerhard Rimpler heard this question and the response to it quite frequently almost ten years ago. However, with the unusual idea of using photovoltaic systems to produce hot water, his company my-PV initiated nothing less than a paradigm shift in solar heat generation. Since then, the guiding principle of "cables instead of pipes" has really shaken up the solar market. The "revolution in solar thermal energy" began in 2014 with the ELWA product! https://www.my-pv.com/de/news/photovoltaikwaerme-vs-solarthermie-kosten-und-flaechenvergleich/ and too www.citybox-solar.com .
According to solar house pioneer Josef Jenni, " ... hot water panels are the gentlest, most environmentally friendly and most efficient technology. "Heat is generated as heat, stored as heat and consumed as heat". Solar thermal energy is collected close to where the heat is needed, for example on the roof of buildings. This heat can also be stored on site relatively easily. In addition, the use of solar thermal energy saves a lot of electricity. The energy transition would therefore primarily be a "heat transition", see www.sonnenhaus-institut.de.
In order to support the 1.5° climate target, the spatial planning authority must take more effective action against further urban sprawl! In addition, sustainable, self-sufficient energy supply must immediately become a new, mandatory building standard.
In general, buildings in rural areas should not be less than 150 m² and should not be less than three storeys high. It would also be right to demand that the "global players" in the retail sector, who have been reclassified as building land and account for a relatively large proportion of soil sealing, and who only build at ground level but on a large scale under a handful of brand or company names on countless village outskirts, be subject to restrictions. They should subsequently add 1 - 3 storeys and a vertical roof garden with generally useful living space. In addition, the car park areas previously sealed with asphalt were to be replaced with functional paving to allow rainwater to be absorbed.
With the costs of building sand and energy sure to continue to rise, there will inevitably be a change in our construction practices. A switch from cement, sand and reinforcing steel to, for example, OSB with EPS insulation - as well as applied PV film façades - would be sustainable, future-proof and therefore desirable.
The installation of vertical wind turbines (Bladeless-Vortex), which have not yet been able to gain acceptance - probably due to the current wind turbine lobby - would also generate energy. The same applies to PV solar films, which should be given preference over heavy silicon panels in aluminium frames.

These approaches could and should also be adopted by the construction industry as well as by the UNHCR, FAO or UNIDO for further implementation.

The most essential, applicable house rules would be: # ... to respect each other. # ... be there for each other as a "small family" and stick together. # ... to help organise the daily structure and group activities as much as possible.
In this example, the central 60 m² of the NurDach serves as a work and recreation room. Small products can be made there in co-operation or various services can be offered.
Smoking and drinking are only permitted outside the building!
Two of the rooms are reserved as an office (or night-time standby room) and as storage - this would result in 18 units of equal size.
Each of the 16 private rooms has 4 m² of living space measuring 3 m x 1.23 m and a room height of 2.5 m and a small window to the day room. Above this is a 3.5 m² attic room, which is accessible via a folding attic staircase.
All sliding doors to the living area can be locked by their respective occupants. In addition to the bed equipment, it also has a wardrobe, folding table, folding chair, a mini-eco-heater, LED lamps and DAB radio with headphones - as well as an attachable extra bed for children who may also move in; and adjustable ventilation.
Residents can keep their sleeping hours around the clock, but there is a general night's rest from 11 pm to 7 am.
The two WCs located in the canopy, the washbasin and the shower have their 12V LED lighting switched by motion sensors.
The shower water is regulated to be drawn every three minutes so that there is enough hot water for everyone. There is also a washing machine and three fridges for residents to use.
In cold weather, the 10 x 6 metre central room of the "NurDach" also provides a place for children and their parents to play and snuggle up. Screens form a partition from the rest of the space, which all residents can use for their various activities.
The kitchen, dining area and sanitary facilities would be located outside under one roof.
The panels hanging down at the outer edge are rolled up in strong winds. These mats are protected against fire and weathering with a coat of water glass.
There is also a children's play tower with 2 swings, sandpit and slide fenced in by Immergrün under this canopy.
The house and porch would also be surrounded by a hedge, raised beds and berry bushes.
Two 1000 litre hot water tanks are located centrally in the porch - they are connected to the hot water collectors on the south-facing roof. This space is also used by a PV module to supply the 12V consumers with electricity.
Leisure activities include badminton, table tennis and a bookshelf as well as sewing, pottery, language courses, music, painting, dance, gymnastics and more. The carers offer a varied, colourful daily structure - according to their own talents and focus. Whether it's an excursion, singing, meditation or a basic PC course - there are always encounters and useful things on the programme.
By coming together on a daily basis to work and spend leisure time together, there are also interdenominational and non-political human conversations.
The project costs a total of around €50,000 per unit.
Most of the goods would come from DIY stores, which would then also appear as the main donors.

ON THE WAY TO THE LIGHT LEAVE NO ONE BEHIND ! Peter Rosegger
- -------------===========------------- -
Solar thermal energy, for example, is a very important building block here, along with other aspects: "Why generate electricity first and then heat from it? That's what solar thermal energy is for." Dr Gerhard Rimpler heard this question and the response to it quite frequently almost ten years ago. However, with the unusual idea of using photovoltaic systems to produce hot water, his company my-PV initiated nothing less than a paradigm shift in solar heat generation. Since then, the guiding principle of "cables instead of pipes" has really shaken up the solar market. The "revolution in solar thermal energy" began in 2014 with the ELWA product! https://www.my-pv.com/de/news/photovoltaikwaerme-vs-solarthermie-kosten-und-flaechenvergleich/ and too www.citybox-solar.com .
According to solar house pioneer Josef Jenni, " ... hot water panels are the gentlest, most environmentally friendly and most efficient technology. "Heat is generated as heat, stored as heat and consumed as heat". Solar thermal energy is collected close to where the heat is needed, for example on the roof of buildings. This heat can also be stored on site relatively easily. In addition, the use of solar thermal energy saves a lot of electricity. The energy transition would therefore primarily be a "heat transition", see www.sonnenhaus-institut.de.
In order to support the 1.5° climate target, the spatial planning authority must take more effective action against further urban sprawl! In addition, sustainable, self-sufficient energy supply must immediately become a new, mandatory building standard.
In general, buildings in rural areas should not be less than 150 m² and should not be less than three storeys high. It would also be right to demand that the "global players" in the retail sector, who have been reclassified as building land and account for a relatively large proportion of soil sealing, and who only build at ground level but on a large scale under a handful of brand or company names on countless village outskirts, be subject to restrictions. They should subsequently add 1 - 3 storeys and a vertical roof garden with generally useful living space. In addition, the car park areas previously sealed with asphalt were to be replaced with functional paving to allow rainwater to be absorbed.
With the costs of building sand and energy sure to continue to rise, there will inevitably be a change in our construction practices. A switch from cement, sand and reinforcing steel to, for example, OSB with EPS insulation - as well as applied PV film façades - would be sustainable, future-proof and therefore desirable.
The installation of vertical wind turbines (Bladeless-Vortex), which have not yet been able to gain acceptance - probably due to the current wind turbine lobby - would also generate energy. The same applies to PV solar films, which should be given preference over heavy silicon panels in aluminium frames.
